Description

  The present invention relates to a control technique, and more particularly to a control method, a control device, a mobile terminal device, and a communication system for controlling communication with a server.

The mobile server connects to the public telephone network via a public radio base station. Since the public telephone network is connected to the Internet via an Internet access point, the mobile server can be accessed from the Internet. However, regardless of whether the mobile server is accessed or not, when the mobile server is connected to the public telephone network, power consumption and radio resources are wasted. Therefore, the mobile server enters a standby state when there is no access, and connects to the public telephone network by receiving an incoming call notification (see, for example, Patent Document 1).

Example 1
Before describing the present invention in detail, an outline will be described. In an embodiment of the present invention, a mobile terminal device is connected by a wireless network such as a mobile network as in a mobile phone communication system, and is also connected by a wired network such as a non-mobile network. About the system. As described above, the mobile terminal device includes an imaging function, a television broadcast receiving function, and the like in addition to a call function, an e-mail function, and a WWW access function. Furthermore, the mobile terminal device also has a server function. In order to control access to such a mobile terminal device, the communication system according to the present embodiment executes the following processing.

  The gateway server is arranged at the boundary between the core network of the communication system and the Internet, and receives a data transmission request for the mobile terminal device from the Internet. An HLR (Home Location Register) is arranged in the core network of the communication system and manages to which paging area the mobile terminal device belongs. Furthermore, in this embodiment, the mobile terminal device reports the operating status of the server function ON / OFF, during a call, during imaging, receiving image, etc. to the HLR, and the HLR registers the operating status of the mobile terminal device. To do.

  When the gateway server receives the data transmission request, it refers to the HLR to obtain the operation status of the mobile terminal device. In addition, the gateway server determines conditions for the operation status of the mobile terminal device, and determines whether to transfer a data transmission request to the mobile terminal device based on the acquired operation status and conditions. For example, when a condition for transferring if a call is not being made is defined, the gateway server determines whether or not to transfer depending on whether or not the status of the mobile terminal device is a call.

  FIG. 1 shows a configuration of a communication system 100 according to Embodiment 1 of the present invention. The communication system 100 includes a mobile terminal device 10, a base station device 12, a gateway exchange 14, an HLR 16, a gateway server 20, a charge management server 22, the Internet 24, and a PC 26. The mobile terminal apparatus 10 includes a terminal antenna 30, and the base station apparatus 12 includes a base station antenna 28.

  The mobile terminal device 10 is also referred to as a mobile phone device or a mobile terminal device, and performs communication with the base station device 12 via the terminal antenna 30. When the wireless communication method between the mobile terminal device 10 and the base station device 12 is, for example, a third generation mobile phone system, the mobile terminal device 10 has the function of the terminal device of the third generation mobile phone system. Have. Since a known technique may be used as a function of the terminal device of the third generation mobile phone system, description thereof is omitted here. Note that the mobile terminal device 10 is generally driven by a battery. The mobile terminal device 10 is connected to a wired network from the base station device 12 to the PC 26 via a wireless network up to the base station device 12.

  The mobile terminal device 10 has (1) a call function, (2) a client function, (3) an internal processing function, and (4) an external connection function. The “client function” corresponds to an electronic mail function, a WWW access function, and the like, and corresponds to a process for accessing a server (not shown). The “internal processing function” corresponds to an imaging process using an imaging function, a playback process using a television receiving function, a playback process using a music playback function, and the like, and corresponds to a process performed by the mobile terminal device 10 alone. The “external connection function” corresponds to a communication function for connecting to an external device (not shown) by a short-range wireless communication system different from the third generation mobile phone system, a wired cable, or the like. An example of an external device (not shown) is a car navigation system.

  Note that the mobile terminal device 10 does not need to include all of (1) to (4), and may include at least one. Here, it demonstrates as what is provided with all. Furthermore, the mobile terminal device 10 also has (5) a server function. The server function is to receive a request from another communication device, for example, the PC 26, and execute processing according to the request. Here, for the sake of clarity, the server function means that the mobile terminal device 10 stores data, and when the data transmission request from the PC 26 is received, the stored data is transmitted to the PC 26. . With such a server function, the mobile terminal device 10 executes HTTP communication with the Web browser provided in the PC 26. The client function and the server function are collectively referred to as a data communication function.

  The base station apparatus 12 includes a base station antenna 28 at one end, and is connected to the mobile terminal apparatus 10 via a wireless network. The base station device 12 is connected from the gateway server 20 to the PC 26 via a wired network at the other end. Here, the space from the base station device 12 to the gateway server 20 corresponds to the core network. The core network corresponds to ATM (Asynchronous Transfer Mode), and the core network and the Internet 24 correspond to the IP protocol. For clarity of explanation, only one base station apparatus 12 is shown here, but actually, a plurality of base station apparatuses 12 are provided. At that time, the base station apparatus 12 is installed such that service areas formed by the base station apparatuses 12 are shifted from each other. Further, a paging area is formed by the base station apparatus 12 installed within a predetermined range.

  The gateway exchange 14 sets a line according to whether the processing performed in the mobile terminal device 10 is a data communication function or a call function. When the processing corresponds to the data communication function, the gateway exchange 14 connects the gateway server 20 and the mobile terminal device 10. On the other hand, when the processing corresponds to the call function, the gateway exchange 14 connects the fixed telephone network (not shown) and the mobile terminal device 10. Such a line setting is made at the timing of a transmission request from the mobile terminal device 10 and an incoming notification to the mobile terminal device 10.

  Here, the operation of line setting when an incoming call notification is input will be described. The gateway exchange 14 inputs an incoming notification from the gateway server 20. The incoming call notification includes an IP address previously assigned to the mobile terminal device 10 that is the destination. The gateway exchange 14 stores the correspondence between the identification number of the mobile terminal device 10 (hereinafter referred to as “mobile terminal device number”) and the IP address, and corresponds to the IP address included in the incoming call notification. The mobile terminal device number is identified. Here, the HLR 16 manages information related to the paging area where the mobile terminal device 10 exists. Specifically, the correspondence between a number for identifying a paging area (hereinafter referred to as “paging area number”) and a mobile terminal device number is managed.

  The gateway exchange 14 specifies a paging area number corresponding to the mobile terminal device number by referring to the HLR 16. The gateway exchange 14 transmits an incoming call notification to the base station apparatus 12 corresponding to the paging area number. As a premise of the above processing, the mobile terminal device 10 performs location registration in advance with respect to the HLR 16, and the result is reflected in the correspondence between the paging area number and the mobile terminal device number. In addition, since a well-known technique should just be used for a location registration, description is abbreviate | omitted here.

  The gateway server 20 is connected to a wired network. Further, the gateway server 20 converts a protocol between the gateway exchange station 14 side, that is, between the gateway server 20 and the mobile terminal device 10, and a protocol between the accounting management server 22 side, ie, between the gateway server 20 and the PC 26. When W-TCP is used on the gateway switching center 14 side and TCP is used on the billing management server 22 side, the gateway server 20 performs conversion between W-TCP and TCP. Since a known technique may be used for such protocol conversion, description thereof is omitted here.

  Further, when receiving a data transmission request for the server function in the mobile terminal device 10, the gateway server 20 obtains the status of the mobile terminal device 10 by accessing the HLR 16 through the gateway exchange 14. As a premise, the mobile terminal device 10 appropriately registers the status for the functions (1) to (5) in the gateway exchange 14. Here, the operation status and the registration process for the functions (1) to (5) will be described later. Further, the gateway server 20 stores in advance conditions for transferring a data transmission request to the mobile terminal device 10. The gateway server 20 determines whether to transfer the data transmission request to the server function in the mobile terminal device 10 based on the acquired operation state and conditions. When the transfer is determined, the gateway server 20 transfers the data transmission request to the mobile terminal device 10 connected via the third generation mobile phone system. On the other hand, when the transfer is not determined, the gateway server 20 returns a message to that effect to the PC 26. The gateway server 20 also has a mail server function.

  The billing management server 22 manages various customer information such as a terminal identification ID for identifying the mobile terminal device 10 that subscribes to the packet communication service of the communication system 100. The billing management server 22 adds billing information to an extension header of data to be transmitted / received in light of predetermined service provision conditions. The billing information includes, for example, a flat-rate billing target, a pay-per-use billing target, a non-billing target, and the like. As described above, the Internet 24 corresponds to the IP protocol, and the PC 26 is connected to the Internet 24. As a result, the Internet 24 connects the PC 26 and the core network.

  In the following description, it is assumed that the PC 26 accesses the gateway server 20 via the Internet 24 and acquires content data stored in the mobile terminal device 10 via the gateway server 20. . At that time, the PC 26 transmits a data transmission request having the destination as the mobile terminal device 10. The data transmission request may be a data transmission request for the client function of the mobile terminal device 10, but here, for the sake of clarity, the data transmission request is a data transmission request for the server function of the mobile terminal device 10. Mainly explained.

  FIG. 2 shows the configuration of the mobile terminal device 10. The mobile terminal device 10 includes a terminal antenna 30, a speaker unit 32, a microphone unit 34, a monitor unit 36, an operation unit 38, a first processing unit 44, a second processing unit 46, a communication unit 48, and a control unit 300.

Output. The speaker unit 32 may output sound to headphones (not shown). When the mobile terminal device 10 performs a call function, the microphone unit 34 inputs a voice uttered by a user of the mobile terminal device 10 and outputs the voice signal as an electrical signal to the control unit 300. The monitor unit 36 is configured by a display and displays contents according to an instruction from the control unit 300. The operation unit 38 is composed of buttons and the like, and receives various instructions from the user. The operation unit 38 outputs the received instruction to the control unit 300. The control unit 300 includes a speaker unit 32, a microphone unit 34, a monitor unit 36, and an operation unit 38, which are input sources and output destinations of information to be communicated, a first processing unit 44 that executes a communication function, and a second process. Data is relayed between the unit 46 and the communication unit 48. In addition, the control unit 300 controls operations for the first processing unit 44 and the second processing unit 46.

  The communication unit 48 performs communication with a base station apparatus 12 (not shown) via the terminal antenna 30. Here, the communication with the base station apparatus 12 is communication corresponding to the third generation mobile phone system, and corresponds to voice communication or data communication. As a result, the communication unit 48 performs communication with a wired network (not shown) via the wireless network. The communication unit 48 also executes a location registration process that is a premise of the above communication, but a description thereof is omitted here. The first processing unit 44 executes the processes (1) to (4) described above. That is, the first processing unit 44 executes processes other than the server function. Further, in association with the configuration of the first processing unit 44, the call processing unit 52 executes the process (1), the client processing unit 54 executes the process (2), and the internal processing unit 308 ( The process 3) is executed, and the external connection unit 306 executes the process (4). On the other hand, the second processing unit 46 executes the process (5) described above.

  The call processing unit 52 executes call processing while using the communication unit 48. For example, the call processing unit 52 executes a call request or an incoming call response as a trigger when starting a call through the communication unit 48 using a known technique. Further, during a call, the call processing unit 52 inputs an audio signal from the microphone unit 34 via the control unit 300. The call processing unit 52 encodes the input audio signal and then outputs the encoded audio signal to the communication unit 48. The communication unit 48 transmits a signal to a telephone device connected to the fixed telephone network via the base station device 12 and the gateway exchange 14 (not shown). On the other hand, the communication unit 48 receives a signal from a telephone device connected to the fixed telephone network via the gateway exchange 14 and the base station device 12 (not shown). The call processing unit 52 inputs a signal from the communication unit 48. The communication unit 48 decodes the input signal and then outputs the signal to the control unit 300 and the speaker unit 32 as an audio signal.

  The client processing unit 54 executes processing as a client while using the communication unit 48. Here, processing as a client includes transmission / reception of electronic mail and WWW access. A known technique may be used for these processes, but the former operation will be briefly described here. When transmitting the e-mail, the client processing unit 54 receives the text of the e-mail to be transmitted from the operation unit 38 via the control unit 300. The client processing unit 54 executes a call request via the communication unit 48.

  After the line is set, the client processing unit 54 transmits e-mail data to the gateway server 20 via the communication unit 48, the base station device 12 (not shown), and the gateway exchange 14. On the other hand, when the communication unit 48 receives an incoming call notification when receiving an e-mail, the client processing unit 54 executes an incoming call response via the communication unit 48. After the line is set, the client processing unit 54 receives e-mail data from the gateway server 20 via the gateway exchange 14, the base station apparatus 12, and the communication unit 48. Further, the client processing unit 54 displays the text of the electronic mail on the monitor unit 36 via the control unit 300. The storage unit 60 stores data used for processing as a client.

  The internal processing unit 308 executes processing that is performed without using the communication unit 48. Here, examples of the internal processing include imaging, television broadcast reception, and music reproduction. The imaging unit 310 generates a captured image and outputs the generated image to the control unit 300 and the storage unit 60. Hereinafter, the image itself or the data format image is referred to as “image” without being distinguished. The image receiving unit 312 includes an antenna (not shown), and receives a terrestrial digital television broadcast signal (hereinafter referred to as “broadcast signal”) via the antenna. Note that ISDB-T (Integrated Services Digital Broadcasting-Terrestrial) and DVB (Digital Video Broadcasting) may be used as terrestrial digital television broadcasting, but the description thereof is omitted here.

  One-segment broadcasting in ISDB-T may be used. The image receiving unit 312 reproduces the program included in the broadcast signal by demodulating the broadcast signal. The image receiving unit 312 outputs the reproduced program to the control unit 300. The reproduction unit 314 acquires music data stored in the control unit 300 and reproduces the music data. Here, the music data is defined in, for example, the MP3 (MPEG Audio Layer-3) format. The reproduction unit 314 outputs the reproduced music data to the control unit 300. Note that instructions regarding activation, operation, and stop of the imaging unit 310, the image receiving unit 312, and the reproduction unit 314 are received from the operation unit 38 via the control unit 300.

(K) relates to whether the external connection unit 306 is communicating with an external device. The monitoring unit 302 outputs the monitoring result of the above combination to the generation unit 304.

  The generation unit 304 receives a monitoring result from the monitoring unit 302. The generation unit 304 generates an information signal from the monitoring result when there is a change in the monitoring result. The information signal can be said to be a signal indicating the operation status of the mobile terminal device 10. FIG. 3 shows the data structure of the information signal generated by the generation unit 304. The information signal is formed by an item column 250 and a content column 252 as illustrated. The item column 250 includes the items (A) to (K) described above, and the content column 252 includes a monitoring result for each item. Returning to FIG. The generation unit 304 transmits an information signal to the HLR 16 (not shown) via the first processing unit 44 and the communication unit 48. This corresponds to registering the status of the mobile terminal device 10 in the HLR 16. Note that the registration may be performed by the same procedure as the location registration, and thus the description thereof is omitted here.

  This configuration can be realized in terms of hardware by a CPU, memory, or other LSI of any computer, and in terms of software, it is realized by a program having a communication function loaded in the memory. Describes functional blocks realized by collaboration. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  FIG. 4 shows the configuration of the gateway exchange 14. The gateway switching center 14 includes a communication unit 70, a switching unit 72, a circuit switching processing unit 74, a packet switching processing unit 76, and a control unit 78. The communication unit 70 connects a base station device 12 (not shown) at one end, and transmits and receives ATM format data to and from the base station device 12. Such data includes data for a call function and data for a data communication function. Further, the communication unit 70 relays data between the exchange unit 72 and the base station apparatus 12 (not shown) by connecting the exchange unit 72 to the other end.

  The circuit switching processing unit 74 connects the switching unit 72 at one end and connects a fixed telephone network (not shown) to the other end. The exchange unit 72 outputs the data input from the exchange unit 72 to the fixed telephone network, and outputs the data input from the fixed telephone network to the exchange unit 72. Here, the data processed in the exchange unit 72 corresponds to the ATM format, and the data processed in the fixed telephone network corresponds to the STM (Synchronous Transfer Mode) format. Therefore, the circuit exchange processing unit 74 converts the data format between the ATM format and the STM format.

  The packet switching processing unit 76 connects the switching unit 72 at one end and connects the gateway server 20 (not shown) to the other end. The packet switching processing unit 76 outputs the data input from the switching unit 72 to the gateway server 20, and outputs the data input from the gateway server 20 to the switching unit 72. Further, the packet exchange processing unit 76 executes a tunneling protocol called GTP.

  The exchange unit 72 sets a line for the mobile terminal apparatus 10 (not shown). The switching unit 72 outputs data input from the circuit switching processing unit 74 or the packet switching processing unit 76 to the communication unit 70, and the data input from the communication unit 70 to the circuit switching processing unit 74 or the packet switching processing unit 76. Output. Further, when receiving an incoming notification from the circuit switching processing unit 74 or the packet switching processing unit 76, the switching unit 72 refers to the information related to the paging area stored in the HLR 16, thereby paging corresponding to the destination of the incoming notification. Identify the area. Moreover, the exchange part 72 outputs an incoming call notification to the base station apparatus 12 included in the paging area.

  When the data transmission request is input from the packet switching processing unit 76, the switching unit 72 refers to the information related to the paging area stored in the HLR 16 to identify the paging area corresponding to the destination of the data transmission request. Moreover, the exchange part 72 outputs a data transmission request to the base station apparatus 12 included in the paging area. Here, in the incoming notification and the data transmission request from the packet switching processing unit 76, the destination is indicated as an IP address. The exchange unit 72 stores the correspondence between the IP address and the mobile terminal device number, and specifies the mobile terminal device number corresponding to the IP address. Also, the exchange unit 72 refers to the HLR 16 based on the mobile terminal device number.

  As a premise of the above processing, the exchange unit 72 receives a location registration request and an information signal from the mobile terminal device 10 (not shown) via the communication unit 70. Further, the exchange unit 72 registers the paging area for the mobile terminal device 10 in the HLR 16 based on the location registration request. Further, the exchange unit 72 registers the operation status of the mobile terminal device 10 in the HLR 16 based on the information signal. These pieces of information registered in the HLR 16 are collectively referred to as “terminal information”. Further, the exchange unit 72 receives an inquiry about terminal information from the gateway server 20 (not shown) via the packet exchange processing unit 76. The exchange unit 72 refers to the HLR 16 in response to the inquiry, and transmits the corresponding terminal information to the gateway server 20 (not shown) via the packet exchange processing unit 76.

  FIG. 5 shows the data structure of the table stored in the HLR 16. As shown in the figure, the mobile terminal device number field 260, the paging area number field 262, the server ON / OFF field 264, the server throughput field 266, the server updating field 268, the mailing field 270, the WWW access field 272, and the calling field 274, an imaging unit operating column 276, an image receiving unit operating column 278, a music playing column 280, a remaining battery level column 282, and an externally connected column 284 are included. In the mobile terminal device number column 260 and the paging area number column 262, paging area numbers corresponding to the respective mobile terminal devices 10 are stored and recorded by location registration. On the other hand, the status corresponding to each mobile terminal device 10 is stored in the server ON / OFF column 264 to the externally connected column 284, and is stored by an information signal. Returning to FIG. The controller 78 controls the operation of the gateway exchange 14.

  FIG. 6 shows the configuration of the gateway server 20. The gateway server 20 includes a protocol conversion unit 140, a mobile terminal device management unit 142, a storage unit 144, and a control unit 146. The mobile terminal device management unit 142 includes an input unit 148, an acquisition unit 150, a determination unit 320, and an output unit 154.

  The protocol conversion unit 140 has one end connected to the gateway server 20 side (hereinafter referred to as “core network side”) and the other end connected to the charge management server 22 side (hereinafter referred to as “Internet side”). As described above, since the core network side corresponds to W-TCP and the Internet side corresponds to TCP, the protocol conversion unit 140 converts both. For example, the protocol conversion unit 140 receives data from the Internet side, converts the data from TCP to W-TCP, and then transmits the data to the core network side. The reverse process is also executed. The mobile terminal device management unit 142 is connected to the protocol conversion unit 140 and determines whether or not to transfer a data transmission request to the second processing unit 46 of the mobile terminal device 10 to the mobile terminal device 10. That is, the mobile terminal device management unit 142 controls the transfer of the data transmission request to the mobile terminal device 10.

  The input unit 148 receives a data transmission request from the PC 26 (not shown) via the protocol conversion unit 140. Such a data transmission request includes a data transmission request to the second processing unit 46 of the mobile terminal device 10 and a data transmission request to the first processing unit 44. Input unit 148 outputs a data transmission request to determination unit 320. When the data transmission request input from the input unit 148 is a data transmission request to the first processing unit 44 in the mobile terminal device 10, the determination unit 320 sends the output unit 154 to the mobile terminal device 10. Transfer the data transmission request. That is, since the determination unit 320 transfers the data transmission request to the first processing unit 44 as it is, it does not control the transfer of the data transmission request. On the other hand, when the data transmission request input from the input unit 148 is a data transmission request to the second processing unit 46 in the mobile terminal device 10, the determining unit 320 is the mobile terminal device that is the destination of the data transmission request. 10 IP addresses are specified.

  The acquisition unit 150 inquires of the gateway exchange 14 via the protocol conversion unit 140 about the terminal information of the mobile terminal device 10 corresponding to the IP address. Upon receiving the inquiry, the gateway exchange 14 converts the IP address into the mobile terminal device number, and then specifies the terminal information by referring to the HLR 16 based on the mobile terminal device number. The acquisition unit 150 receives terminal information from the gateway exchange 14 via the protocol conversion unit 140. That is, the acquisition unit 150 acquires the operation status of the mobile terminal device 10 from a table arranged in the HLR 16 on the core network and showing the operation status of each mobile terminal device 10.

  As described above, the table referred to in the acquisition unit 150 includes the operation status of the first processing unit 44, the operation status of the second processing unit 46, and the paging of the mobile terminal device 10 as the operation status of the mobile terminal device 10. The area is shown. In addition, the table referred to in the acquisition unit 150, that is, the table stored in the HLR 16 is appropriately updated by the mobile terminal device 10. The acquisition unit 150 outputs the acquired terminal information to the determination unit 320.

  The storage unit 144 stores in advance conditions for transferring a data transmission request to the mobile terminal device 10. An example of the condition is that a call is not made in the call processing unit 52 in the mobile terminal device 10. FIG. 7 shows the data structure of the conditions stored in the storage unit 144. As shown in the figure, the mobile terminal apparatus number column 400, the paging area number column 402, the server ON / OFF column 404, the server processing amount column 406, the server updating column 408, the mail column 410, the WWW access column 412, and the call column 414, an imaging unit operating column 416, an image receiving unit operating column 418, a music playing column 420, a remaining battery level column 422, and an externally connected column 424 are included.

  For example, the server ON / OFF field 404 includes conditions for the server ON / OFF field 264 of FIG. 5 as “A1 ′” and “A2 ′” for each mobile terminal device 10. Here, the conditions for the mobile terminal device 10 having the mobile terminal device number “C1” are included as “A1 ′” and “B1 ′” for all of the paging area number column 402 to the externally connected column 424. However, a condition may be set only in a part of the paging area number column 402 to the externally connected column 424. The conditions included in the paging area number column 402 correspond to conditions for the existing position.

  The conditions included from the server ON / OFF column 404 to the server updating column 408 correspond to conditions for the second processing unit 46. The mail middle column 410 and the WWW access column 412 correspond to conditions for the client processing unit 54. The on-call column 414 corresponds to a condition for the call processing unit 52. The imaging unit operating column 416 to the remaining battery level column 422 correspond to conditions for the internal processing unit 308. The external connection column 424 corresponds to a condition for the external connection unit 306. Further, conditions are defined for each mobile terminal device 10. Such a condition may be set by the user via the mobile terminal device 10 or may be set by a communication carrier via a communication device (not shown). Returning to FIG.

  The determination unit 320 receives terminal information for the mobile terminal device 10 that can be a transfer destination from the acquisition unit 150. This corresponds to receiving the operation status of the mobile terminal device 10. In addition, the determining unit 320 refers to the storage unit 144 to acquire a condition for the mobile terminal device 10. The determination unit 320 determines transfer based on the operation status and conditions. More specifically, the determination unit 320 determines transfer if the operation status satisfies the condition. As described above, since the operation status and the condition are configured by a plurality of items, the determination unit 320 determines the transfer when all the operation statuses satisfy the condition. Note that the determination unit 320 may determine transfer when the number of operating situations that satisfy the condition is greater than a predetermined number. As a result of such processing, for example, the determination unit 320 transfers the data transmission request to the second processing unit 46 based on the operation status of the first processing unit 44 and the conditions for the first processing unit 44. decide. Further, the determination unit 320 determines the transfer of the data transmission request to the second processing unit 46 based on the presence position of the mobile terminal device 10 and the condition for the presence position of the mobile terminal device 10.

  The output unit 154 transmits a data transmission request to the mobile terminal device 10 via the gateway switching station 14 and the base station device 12 via the protocol conversion unit 140 when the determination unit 320 determines the transfer. In particular, the output unit 154 transfers the data transmission request to the second processing unit 46 in the mobile terminal device 10. On the other hand, the output unit 154 transmits a message to the PC 26 that is the transmission source of the data transmission request via the protocol conversion unit 140 when the transfer is not determined by the determination unit 320. This message is a message when transfer is not determined. FIGS. 8A to 8B show messages when the determination unit 320 does not determine transfer. As shown in FIG. 8A, the message is indicated as “Currently unable to respond”. Further, as shown in FIG. 8B, the message may be indicated as “cannot answer because the call is currently in progress”. In other words, the user is notified of the reason for not being able to respond by clearly specifying items that do not satisfy the condition in the determination unit 320.

  The operation of the communication system 100 configured as above will be described. FIG. 9 is a sequence diagram showing a procedure for registering the status of the mobile terminal device 10 in the communication system 100. When the mobile terminal device 10 detects the transition of the operation status (S10), the mobile terminal device 10 generates an information signal (S12). A line between the mobile terminal device 10 and the gateway exchange 14 is set (S14). The mobile terminal device 10 transmits an information signal to the gateway exchange 14 (S16). The gateway exchange 14 registers the operation status of the mobile terminal device 10 in the HLR 16 (S18). The gateway exchange 14 notifies the registration to the mobile terminal device 10 (S20).

  FIG. 10 is a sequence diagram illustrating a data transmission procedure in the communication system 100. The PC 26 transmits a data transmission request to the gateway server 20 (S40). The gateway server 20 transmits a terminal information inquiry to the gateway exchange 14 (S42), and the gateway exchange 14 transmits a response of the terminal information to the gateway server 20 (S44). The gateway server 20 determines the transfer of the data transmission request (S46). The gateway server 20 transmits a data transmission request to the gateway exchange 14 (S48), and the gateway exchange 14 transmits a data transmission request to the mobile terminal device 10 (S50). The mobile terminal device 10 transmits data to the gateway exchange 14 (S52), the gateway exchange 14 transmits data to the gateway server 20 (S54), and the gateway server 20 transmits data to the PC 26 ( S56).

  FIG. 11 is a flowchart showing a procedure for registering the status of the mobile terminal device 10 in the mobile terminal device 10. If the monitoring unit 302 does not detect the transition of the operation status (N in S70), the monitoring unit 302 stands by. On the other hand, if the monitoring unit 302 detects the transition of the operation status (Y in S70), the generation unit 304 generates an information signal (S72). The first processing unit 44 and the communication unit 48 set up a line with the base station apparatus 12 (S74), and transmit an information signal to the gateway exchange 14 (S76). Further, the control unit 300 receives a registration notification from the gateway exchange 14 via the communication unit 48 and the first processing unit 44 (S78).

  FIG. 12 is a flowchart showing a procedure for registering the status of the mobile terminal device in the gateway exchange 14. If the exchange unit 72 does not receive an information signal from the mobile terminal device 10 via the communication unit 70 (N in S90), the exchange unit 72 stands by. On the other hand, when the exchange unit 72 receives the information signal from the mobile terminal device 10 via the communication unit 70 (Y in S90), based on the mobile terminal device number included in the information signal, the exchange unit 72 The terminal information is updated (S92). The exchange unit 72 transmits a registration notification to the mobile terminal device 10 via the communication unit 70 (S94).

  FIG. 13 is a flowchart showing a procedure for transferring a data transmission request in the gateway server 20. The input unit 148 receives a data transmission request addressed to the mobile terminal device 10 via the protocol conversion unit 140 (S110). The acquisition unit 150 inquires of the gateway exchange 14 about the terminal information via the protocol conversion unit 140 (S112) and receives a terminal information response (S114). If the operation status included in the terminal information satisfies the condition (Y in S116), the determination unit 320 determines the transfer of the data transmission request to the mobile terminal device 10 (S118). The output unit 154 transfers the data transmission request via the protocol conversion unit 140 (S120). The protocol conversion unit 140 receives the data (S122) and transmits the data to the PC 26 (S124). On the other hand, if the operation status included in the terminal information does not satisfy the condition (N in S116), the output unit 154 notifies the PC 26 that the response cannot be made via the protocol conversion unit 140 (S126).

  According to the embodiment of the present invention, when a data transmission request to the second processing unit in the mobile terminal device is received, the data transmission request is transferred based on the operation status and conditions in the mobile terminal device. Therefore, it is possible to control access while considering the operation status of the mobile terminal device. In addition, since access is controlled while considering the operation status of the mobile terminal device, it is possible to suppress a decrease in convenience of the mobile terminal device even when the server function is installed in the mobile terminal device. In addition, when a data transmission request to the second processing unit in the mobile terminal device is received, transfer is determined based on the operation status of the first processing unit, so the operation of the first processing unit in the mobile terminal device Can be reduced.

  In addition, when a data transmission request to the second processing unit in the mobile terminal device is received, the transfer is determined based on the location of the mobile terminal device, so that traffic can be controlled according to the location. In addition, since the terminal information stored in the HLR is updated by the mobile terminal device, a new situation can be reflected. Moreover, since a new situation is reflected, access control can be appropriately executed. Further, since the terminal information is registered in advance in the HLR, the processing can be immediately executed when a data transmission request is received. Further, since access control is executed in the core network, conditions can be easily set not only by the user but also by the communication carrier. Further, although access control is executed in response to a data transmission request to the second processing unit, access control is not executed on a signal to the first processing unit, so that the influence on the operation of the first processing unit can be reduced. .

(Example 2)
The second embodiment of the present invention relates to a communication system including a mobile terminal device having a server function, as in the first embodiment. In the first embodiment, access control for the server function of the mobile terminal device is executed by the gateway server. That is, the gateway server controls whether the data transmission request to the server function is transferred to the mobile terminal device. At that time, the gateway server determines whether or not to transfer based on the operation status of the mobile terminal device and the conditions for the operation status. On the other hand, in the second embodiment, the mobile terminal device itself executes access control for the server function. That is, the mobile terminal device stores the conditions for the operation status in advance, and when acquiring the operation status, determines whether to respond to the data transmission request based on the operation status and the conditions. The communication system 100 according to the first embodiment is of the same type as that in FIG. 1, but here, the difference will be mainly described.

  FIG. 14 shows the configuration of the mobile terminal apparatus 10 according to the second embodiment of the present invention. In the mobile terminal device 10 shown in FIG. 14, the configuration of the control unit 300 is different from that of the mobile terminal device 10 shown in FIG. 2. The control unit 300 includes a situation grasping unit 330, a condition setting unit 332, and a receiving unit 334. The receiving unit 334 receives a data transmission request from the PC 26 (not shown) via the communication unit 48, the server processing unit 56, or the client processing unit 54. If the received data transmission request is a data transmission request to the second processing unit 46, the reception unit 334 outputs the data transmission request to the determination unit 336. On the other hand, when the received data transmission request is a data transmission request to the first processing unit 44, the reception unit 334 instructs the first processing unit 44 to respond to the data transmission request. That is, since the reception unit 334 processes the data transmission request to the first processing unit 44 as it is, like the input unit 148 in FIG. 6, it does not control the response to the data transmission request.

  The status grasping unit 330 manages the operation status of the first processing unit 44 and the second processing unit 46 as well as the location of the mobile terminal device 10, as with the monitoring unit 302 of FIG. 2. Hereinafter, these are referred to as “operational status of the mobile terminal device 10”. Managing the location of the mobile terminal device 10 may be managing the connected base station device 12. Further, the operation status of the first processing unit 44 and the second processing unit 46 may be, for example, the combination of (A) to (K) described above or at least one of them. Another item may be included. The situation grasping unit 330 outputs the operation situation of the mobile terminal device 10 to the determining unit 336.

  The condition setting unit 332 stores in advance conditions for causing the second processing unit 46 to respond to the data transmission request. The conditions for causing the second processing unit 46 to respond to the data transmission request are the conditions for the operation status of the first processing unit 44 and the conditions for the operation status of the second processing unit 46, as in the storage unit 144 of FIG. It is defined as a condition for the location of the mobile terminal device 10. That is, the condition for causing the second processing unit 46 to respond to the data transmission request is defined as a condition for the operation status of the mobile terminal device 10. Such conditions are set by the user via the operation unit 38. The condition setting unit 332 outputs the condition to the determination unit 336.

  When the determination unit 336 receives a data transmission request from the reception unit 334, the determination unit 336 receives an operation state from the state grasping unit 330 and a condition from the condition setting unit 332. The determination unit 336 determines whether to output a data transmission request to the second processing unit 46 based on the operation status and conditions. More specifically, the determination unit 336 determines an output if the operation status satisfies a condition. As described above, since the operation status and the condition are configured by a plurality of items, the determination unit 336 determines the output when all the operation statuses satisfy the condition. Note that the determination unit 336 may determine the output when the number of operating situations that satisfy the condition is greater than a predetermined number.

  As a result of such processing, for example, the determination unit 336 outputs a data transmission request to the second processing unit 46 based on the operation status of the first processing unit 44 and the conditions for the first processing unit 44. decide. Further, the determination unit 320 determines the output of the data transmission request to the second processing unit 46 based on the location of the mobile terminal device 10 and the conditions for the location of the mobile terminal device 10. The server processing unit 56 transmits the data stored in the storage unit 58 from the communication unit 48 in response to the data transmission request. On the other hand, when the determination unit 320 does not determine the output of the data transmission request to the second processing unit 46, the determination unit 336 passes through the second processing unit 46 and the communication unit 48, as shown in FIG. A message not to execute the response as shown in (b) is output to the PC 26.

  The operation of the communication system 100 configured as above will be described. FIG. 15 is a flowchart showing a response procedure for the received signal in the mobile terminal device 10. The accepting unit 334 receives a signal via the first processing unit 44 or the communication unit 48 (S140). If the received signal is a data transmission request to the second processing unit 46 (Y in S142), the situation grasping unit 330, the condition setting unit 332, and the determination unit 336 execute a response determination process (S144). On the other hand, if the received signal is not a data transmission request to the second processing unit 46 (N in S142), the first processing unit 44 executes processing for incoming or incoming calls (S146).

  FIG. 16 is a flowchart showing the procedure of the response determination process in the mobile terminal device 10. When the reception unit 334 receives the data transmission request (S160), the determination unit 336 receives the operation status of the mobile terminal device 10 from the status grasping unit 330 and the condition setting unit 332. If the operating condition satisfies the condition (Y in S162), the determination unit 336 outputs a data transmission request to the second processing unit 46 (S164). Further, the second processing unit 46 transmits data via the communication unit 48 (S166). On the other hand, if the operating condition does not satisfy the condition (N in S162), the determination unit 336 transmits a message indicating that a response cannot be made via the communication unit 48 (S168).

  According to the embodiment of the present invention, when a data transmission request to the second processing unit is received, whether to respond to the data transmission request is determined based on the operation status and conditions in the mobile terminal device. The mobile terminal device can control access to itself. In addition, since it is determined whether to respond to the data transmission request based on the operation status in the mobile terminal device, the influence on other processing can be reduced even when the server function is installed in the mobile terminal device. . In addition, when receiving a data transmission request to the second processing unit in the mobile terminal device, it is determined whether to respond based on the operation status of the first processing unit, and therefore the influence on the operation of the first processing unit. Can be reduced.

  In addition, when receiving a data transmission request to the second processing unit in the mobile terminal device, it is determined whether to respond based on the location of the mobile terminal device. You can easily set a place that you do not want to let. Moreover, since access is controlled in the mobile terminal device, processing in the core network can be reduced. Further, although access control is executed in response to a data transmission request to the second processing unit, access control is not executed on a signal to the first processing unit, so that the influence on the operation of the first processing unit can be reduced. .

(Example 3)
The third embodiment of the present invention also relates to a communication system including a mobile terminal device having a server function, similar to the first embodiment. In the first embodiment, when the gateway server determines not to transfer, the gateway server notifies the fact. On the other hand, in Example 3, a clone server is installed in the core network. Data stored in the mobile terminal device is duplicated in the clone server. The gateway server transfers the data transmission request to the clone server without transferring the data transmission request to the mobile terminal device.

  FIG. 17 shows a configuration of a communication system 100 according to the third embodiment of the present invention. The communication system 100 shown in FIG. 17 adds a clone server 18 to the communication system 100 shown in FIG. When the gateway server 20 determines not to transfer the data communication request to the mobile terminal device 10, the gateway server 20 transfers the data communication request to the clone server 18. The clone server 18 is connected to a core network, for example, a packet communication network installed by a communication carrier. Only one clone server 18 may be arranged, or a plurality of clone servers 18 may be arranged in a distributed manner.

  Here, when distributed in a plurality, the data may be replicated as it is to the plurality of clone servers 18 or may be fragmented and copied to the plurality of clone servers 18. In the case of fragmentation, for example, P2P (Peer to Peer) technology is used for fragmenting data and using fragmented data. The clone server 18 substitutes a server function in the mobile terminal device 10 by replicating at least a part of the data stored in the mobile terminal device 10 at a predetermined timing. Here, the content of the data stored in the clone server 18 may not completely match the content of the data stored in the mobile terminal device 10. Therefore, the data stored in the clone server 18 may be a part of data stored in the mobile terminal device 10 or data previously stored in the mobile terminal device 10.

  Specifically, the clone server 18 receives the data transmission request from the gateway server 20 to perform the server function of the mobile terminal device 10 and transmits the data to the PC 26. For example, the clone server 18 performs the server function when the gateway server 20 does not transfer a data communication request to the mobile terminal device 10. Note that the clone server 18 holds not only the content data in the mobile terminal device 10 but also a message as shown in FIGS. 8A to 8B and may transmit it to the PC 26 instead of the data. .

  FIG. 18 shows the configuration of the clone server 18. The clone server 18 includes a communication unit 110, a clone processing unit 112, and a control unit 122. The clone processing unit 112 includes a data receiving unit 114, a server processing unit 116, a management unit 118, and a storage unit 120.

  The communication unit 110 is arranged in the core network, connects the gateway exchange 14 (not shown) at one end, and connects the gateway server 20 (not shown) to the other end. If the destination of the received data is not the clone server 18, the communication unit 110 transmits the data as it is. That is, the communication unit 110 outputs the data from the gateway exchange 14 to the gateway server 20 as it is, and outputs the data from the gateway server 20 to the gateway exchange 14 as it is. The data receiving unit 114 performs communication with the mobile terminal device 10 via the gateway 110 and the base station device 12 via the communication unit 110. The data reception unit 114 receives at least part of the data stored in the mobile terminal device 10 from the mobile terminal device 10. At that time, the mobile terminal device number or IP address corresponding to the mobile terminal device 10 is also received. A combination of the mobile terminal device number and the IP address may be received. Further, a URL (Uniform Resource Locator) made up of a character string may be used instead of the IP address, but these are used without distinction below.

  The data reception unit 114 outputs the received data, IP address, and the like to the management unit 118, and the management unit 118 stores the data in the storage unit 120 while associating the data with the IP address and the like. As a result, the storage unit 120 stores data while associating with the mobile terminal device 10. This is equivalent to duplicating data stored in the mobile terminal device 10. The storage unit 120 also stores messages such as those shown in FIGS. The server processing unit 116 executes the same processing as that of the server processing unit 56 in the mobile terminal device 10 (not shown). The server processing unit 116 receives a data transmission request from the gateway server 20 (not shown) via the communication unit 110.

  This data transmission request is originally transmitted from the PC 26 (not shown) to the mobile terminal device 10, and the gateway server 20 changes the destination from the mobile terminal device 10 to the clone server 18. Therefore, the data transmission request includes information related to the mobile terminal device 10 that is the original destination. The information regarding the mobile terminal device 10 corresponds to the above-described mobile terminal device number or IP address, or a combination thereof. The server processing unit 116 requests the management unit 118 to extract data corresponding to the data transmission request. The management unit 118 extracts the data of the mobile terminal device 10 corresponding to the data transmission request from the storage unit 120 and outputs the extracted data to the server processing unit 116. The server processing unit 116 transmits data to the gateway server 20 and the PC 26 via the communication unit 110. Thus, since the server processing unit 116 transmits data according to the data transmission request, it can be said that the server function in the mobile terminal device 10 is performed as a proxy. The management unit 118 may extract the message stored in the storage unit 120, and the server processing unit 116 may transmit the message to the gateway server 20 and the PC 26 via the communication unit 110. The control unit 122 controls the operation of the clone server 18.

  The operation of the communication system 100 configured as above will be described. FIG. 19 is a sequence diagram illustrating a content data duplication procedure in the communication system 100. Content data is created in the mobile terminal device 10 (S210). The mobile terminal device 10 provides content data (S212). This corresponds to setting content data as a reproduction target. The mobile terminal device 10 confirms the communication state of the clone server 18 via the base station device 12 (S214). If the traffic volume in the clone server 18 is smaller than the threshold value, the mobile terminal device 10 transmits content data to the clone server 18 (S216). The clone server 18 stores content data in association with the mobile terminal device 10 (S218).

  FIG. 20 is a sequence diagram illustrating a data transmission procedure in the communication system 100. The PC 26 transmits a data transmission request to the gateway server 20 (S290). The gateway server 20 transmits a terminal information inquiry to the gateway exchange 14 (S292), and the gateway exchange 14 transmits a response of the terminal information to the gateway server 20 (S294). The gateway server 20 determines not to transfer the data transmission request to the mobile terminal device 10 (S296). The gateway server 20 transmits a data transmission request to the clone server 18 (S298), and the clone server 18 transmits data to the gateway server 20 (S300). The gateway server 20 transmits data to the PC 26 (S302). The PC 26 receives the data (S304). Here, the data from step 300 to step 304 may be a message.

  FIG. 21 is a flowchart showing a procedure for transferring a data transmission request in the gateway server 20. Since steps 310 to 324 in FIG. 21 are the same as steps 110 to 124 in FIG. 13, description thereof is omitted here. If the operation status included in the terminal information does not satisfy the condition (N in S316), the output unit 154 outputs a data transmission request to the clone server 18 via the protocol conversion unit 140 (S326). The third embodiment may be applied to the second embodiment. In the third embodiment, the gateway server 20 has determined whether to transfer a data transmission request to the mobile terminal device 10, but the mobile terminal device 10 determines whether to respond to the data transmission request. If it is determined not to respond, the mobile terminal device 10 transfers a data transmission request to the clone server 18.

  According to the embodiment of the present invention, when the condition for transferring the data transmission request to the mobile terminal device is not satisfied, the clone server is made to respond to the data transmission request, so that the convenience for the user can be improved. . In addition, since the response to the data transmission request is made to the clone server, the processing amount of the gateway server can be reduced. In addition, since the clone server changes to a mobile terminal device and transmits data, the reliability of the system can be improved.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .

  In the first embodiment of the present invention, the terminal information is stored in the HLR 16. However, the present invention is not limited to this. For example, the terminal information may be stored not in the HLR 16 but in another device arranged in the core network. Therefore, the terminal information may be stored in the storage unit 144 of the gateway server 20. In that case, the acquisition unit 150 acquires terminal information from the storage unit 144. According to this modification, the degree of freedom of the configuration of the communication system 100 can be improved.

  In the first to third embodiments of the present invention, the determination unit 320 and the determination unit 336 determine a transfer and a response when the operation status satisfies a condition. However, without being limited thereto, for example, the determination unit 320 and the determination unit 336 may determine not to transfer or respond when the operation state does not satisfy the condition. According to this modification, the degree of freedom for setting conditions can be improved.

  Embodiments 1 to 3 of the present invention may be arbitrarily combined. For example, the gateway server 20 and the mobile terminal device 10 may execute access control for the second processing unit. According to this modification, it is possible to obtain the effect of any combination of the first to third embodiments of the present invention.
